1. Max. input current is calculated according to the low voltage input of 176V and 100% load percentage.
2. Max. output/bypass current is calculated according to the rated voltage and 100% load percentage.
3. The battery discharge current at the lowest battery voltage is calculated according to the battery cell number of 30
and lowest EOD voltage of1.6V.
